No software with hollow copper bar kg said, can calculate the weight of it?
The hollow part is flexibleChasing the answerHollow is cylindrical? To measure the radius of the hollow, calculated from this part of the volume, and the total volume of copper minus this one, multiplied by the proportion on the line.
Is the hollow part regular? If it is regular, the weight (mass) of the hollow part can be calculated as long as the volume of the hollow part is calculated.
Pure copper, then use the drainage method to calculate the volume, it will calculate the weight. The regular shape is directly taken into account and the volume comes out. The irregular can only be drainedAskNot pure barrels, accounting for about seventy percentChasing the answerThere is no density, no way to calculate, but often get this kind of things, there should be an experience density value
